I think I got it in the second or third try....no worries... >_<;;
Is it hard? Maybe I'm just a natural.

Um, I found that I'd remember the sounds of the notes, make it into a song in your head. Even hum it as you go, that might help ya.

Maybe its just because I know the sounds of the notes quite well, since I like hearing them and stuff.
And remember: its not so hard to remember 8 notes since you re-do the first ones over and over, so try to remember clearly what you heard those 7 other times you went through and then all you have to remember is the last note.

Good luck.
